Molecular weight : 119
Chemical formulation : C6H5N3
CAS NO. :95-14-7
Properties:
white needle-shape crystalloids, it can be processed to be big
flake, column, fine granular,
powder. It's bitter, odorless, boiling point is
204ºC(15mmHG),soluble in alcohol, benzene, toluene,
chloroform and dimethylformamide, and slightly soluble in water.
Specifications:
Guide name | Guid |
Purity | ≥99.8% |
Chroma | ≤NO.40 |
Moisture | ≤0.04% |
Melting point | ≥97°C |
Ash content | ≤0.03% |

Application:
It's mainly used as rust-preventer,antifreezing liquid,antioxidant
additive(including
lubricating oil,hydraulic oil,brake oil,transformer's
oil),emugent,water stabilizer,the additive for high
molecular materials'(polyester and polyesteramide)capacity of
ultraviolet resistance and anstatic
electricity,photographic antifogging agent,copper mine
flotation,metal's slow corrosion etc.It can be used in combination
with a variety of scale inhibitors and bactericidal algaecides, and
benzotriazazole does not interfere with the corrosion inhibition of
polyphosphate, and has strong resistance to oxidation. However,
when it is present with free chlorine, it loses its corrosion
inhibition effect on copper, and after the chlorine disappears, its
corrosion inhibition is restored. Its use concentration is
generally 1-2mg/L, and the corrosion inhibition effect is very good
in the range of pH value 5.5~10, but the corrosion inhibition
effect is reduced in the medium with low pH value.
